Wildlife trade is a key driver of the biodiversity crisis. Unregulated, or under-regulated wildlife can lead to unsustainable exploitation wild populations. International efforts regulate mostly miss 'lower-value' species, such as those imported pets, resulting in limited knowledge groups like reptiles. Here we generate dataset on web-based private commercial reptiles highlight scope global reptile trade. We find that over 35% species are traded online. Three quarters this not covered by...
Wildlife trade is a major driver of biodiversity loss, yet whilst the impacts in some species are relatively well-known, taxa, such as many invertebrates often overlooked. Here we explore global patterns arachnids, and detected 1,264 from 66 families 371 genera trade. Trade these groups exceeds millions individuals, with 67% coming directly wild, up to 99% individuals genera. For popular tarantulas 50% trade, including 25% described since 2000. CITES only covers 30 (2%) potentially traded....
The unsustainable use of wildlife is a primary driver global biodiversity loss. No comprehensive dataset exists on what species are in trade, their geographic origins, and trade’s ultimate impacts, which limits our ability to sustainably manage trade.

As the biodiversity crisis continues, we must redouble efforts to understand and curb pressures pushing species closer extinction. One major driver is unsustainable trade of wildlife. Trade in internationally regulated gains most research attention, but this only accounts for a minority traded risk failing appreciate scale impacts unregulated legal trade. Despite being legal, puts pressure on wild via direct collection, introduced pathogens, invasive species. Smaller species-rich...
Home range estimators are a critical component for understanding animal spatial ecology. The choice of home estimator in ecology studies can significantly influence management and conservation actions, as different methods lead to vastly interpretations movement patterns, habitat selection, well requirements. Reptile particular have struggled reach consensus on the appropriate use, species with cryptic behavior make assessment difficult. We applied dynamic Brownian Bridge Movement Models...
Animal movement expressed through home ranges or space-use can offer insights into spatial and habitat requirements. However, different classes of estimation methods are currently instinctively applied to answer range, movement-based research questions regardless their widely varying outputs, directly impacting conclusions. Recent technological advances in animal tracking (GPS satellite tags), have enabled new quantify pathways, but so far primarily targeted mammal avian species. Most...
Abstract Background Studying animal movement provides insights into how animals react to land-use changes. As agriculture expands, we can use examine change their behaviour in response. Recent reviews show a tendency for mammalian species reduce movements response increased human landscape modification, but reptile have not been as extensively studied. Methods We examined of large reptilian predator, the King Cobra ( Ophiophagus hannah ), Northeast Thailand. used consistent regime radio...
Animal movement and resource use are tightly linked. Investigating these links to understand how animals space select habitats is especially relevant in areas affected by habitat fragmentation agricultural conversion. We set out explore the selection of Burmese pythons (Python bivittatus) a heterogenous, landscape within Sakaerat Biosphere Reserve, northeast Thailand. used VHF telemetry record daily locations seven created dynamic Brownian Bridge Movement Models produce occurrence...
Protected areas are often promoted as an important solution to preserving biodiversity. However, permeable edges can undermine the effectiveness of preserves because animals may move into adjacent human-dominated unprotected areas. We investigated attitudes toward, and sources mortality of, a far-ranging apex predator, king cobra ( Ophiophagus hannah; Cantor 1836), in biosphere reserve northeastern Thailand. Our questionnaire revealed marked fear snakes hostility toward cobras. Using...
Abstract A species’ spatial ecology has direct implications for that conservation. Far-ranging species may be more difficult to conserve because their movements increase chances of encountering humans. The can take them out protected areas, which is especially risky are routinely persecuted. king cobra ( Ophiophagus hannah ), a large venomous elapid, subject anthropogenic pressures, such as persecution and habitat loss. Here we present results from study using radio telemetry quantify use...
A species’ distribution provides fundamental information on: climatic niche, biogeography, and conservation status. Species models often use occurrence records from biodiversity databases, subject to spatial taxonomic biases. Deficiencies in data can lead incomplete species estimates. We incorporate other sources supplement datasets. The general public is creating (via GPS-enabled cameras photograph wildlife) incidental that may present an opportunity improve models. investigated (1) of a...

Global road networks continue to expand, and the wildlife responses these landscape-level changes need be understood advise long-term management decisions. Roads have high mortality risk snakes because typically move slowly can intentionally targeted by drivers.We investigated how radio-tracked King Cobras (
Saltwater crocodiles Crocodylus porosus are listed as critically endangered in Myanmar because they limited to Meinmahlakyun Wildlife Sanctuary (MKWS) the Ayeyarwady delta region. Little contemporary data exists on their distribution and population size which hinders effective conservation management.

The response of venomous snakes to anthropogenic landscape disturbance remains scarcely studied in tropical regions. Green pit vipers are among the most diverse Southeast Asian tropics and bite highest number people any group where they found, yet conservation snakebite management efforts have been hindered by limited prior studies these organisms both natural anthropogenically disturbed landscapes. Subsequently, we sought address key knowledge gaps regarding persistence green disturbance....
Wild King Cobras, Ophiophagus hannah, are known to prey almost exclusively on snakes. We observed opportunistic ingestion of a plastic bag by radio-tracked adult male O. which was detrimental the health individual and likely lead its death. Our observation demonstrates that improper disposal food waste can be threat snakes, highlighting need maintain waste-free environment, especially in areas inhabited vulnerable species.
Abstract To prevent population extirpations, we need to understand a species’ requirements, especially for critically endangered species inhabiting biodiversity hotspots. Studying animal movement provides necessary insights and gauges protected area effectiveness. Southeast Asian areas are becoming isolated, stressing the maintaining viability. We used radio‐telemetry with Elongated Tortoise ( Indotestudo elongata ) assess: movements, space use, conspecific overlap in small area—Sakaerat...
Abstract The Big-Eyed Green Pit Viper ( Trimeresurus macrops ; Kramer, 1977) is a venomous snake species endemic to Southeast Asia. Although we have some knowledge of the systematics and toxicology T. , little known about spatial ecology this species. From May 2013 February 2014, used radio-telemetry determine home-range sizes 13 adult female inhabiting Sakaerat Biosphere Reserve in Northeast Thailand. We found that individual home ranges for averaged 0.175 ha, with activity areas ranging...
Thailand is a world biodiversity hotspot with 176 known snake species. However, anthropogenic influences on snakes associated growing human populations are poorly understood. Aquatic funnel traps (AFTs) in widespread use agricultural areas throughout Thailand, and they have the ability to collect large quantities of by-catch, including snakes. During an on-going study human-snake conflict we found, using radio-telemetry, one our radio-tracked Bungarus candidus (Malayan Krait) individuals...
Predator-prey interactions are fundamental drivers of population dynamics. Studying both predator and prey species simultaneously yields particularly useful insights into these complex interactions. Despite being significant, widespread avian nest predators, Southeast Asian snakes rarely studied in relation to prey. The Green Cat Snake Boiga cyanea is a primary predator, estimated be responsible for 17–33% forest songbird depredations Northeast Thailand. We explored diurnal nocturnal...
